Got mine installed last Sunday. Learned it will throw a code and put the truck in limp mode , when put into any of the eco modes. After clearing both and it still being in a eco mode . After starting the truck and still in park. I changed the setting to city -4. Sure enough got a code and truck put it self in limp mode again. Shutting the eng off and restarting clears the limp mode but not the ck eng light.
That will clear if battery is disconnected for about 2 mins. Need to spent the time playing with this more to see if it's going to throw a code everytime the settings are changed. Since I made the changes while the eng was still cold that might be the issue. Will know more as time goes on. Over all for its main purpose being the sport and sport + modes , it works as advertised. Hooo Yea !
